Chemical Structure
Description
CATO supplies 4-Bromo-6-chloro-3-nitroquinoline (CAS 1654738-13-2), a certified reference material (molecular formula C9H4BrClN2O2, MW 287.50 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-6-chloro-3-nitroquinoline (C9H4BrClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-Bromo-6-chloro-3-nitroquinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
